Abstract: MULTICHANNEL SUBSCRIPTION TELEVISION SYSTEM by Robert A. Sherwood ABSTRACT OF DISCLOSURE           Sinusoidal timing reference signals, each of which is associated with a different suppressed-sync scrambled-priority television channel signal, frequency modulate associated carrier frequency signals for producing modulated carrier signals that are combined with a continuous wave (CW) sinusoidal carrier frequency signal.  After low-pass filtering to block harmonic frequencies that may interfere with the video carriers of composite television signals, only the fundamentals of the CW and modulated carrier signals are combined with non-scrambled and/or scrambled composite television signals for transmission to subscriber's equipment.  In a descrambler at a subscriber location, the CW carrier signal is mixed with the modulated carrier signals to produce frequency modulated IF signals containing timing information for associated priority television channel signals.  Upon request of a subscriber, a particular IF signal is demodulated to reproduce a timing reference signal here that is operated or to produce timing pulses that are slightly wider than the pulse width of, and delayed in time with respect to, suppressed horizontal blanking pulses carrying synchronization pulses in the associated scrambled composite television signal.  The timing pulses drive a switched attenuator or amplifier for restoring the level of suppressed horizontal synchronization and blanking pulses in the associated scrambled composite television signal, and thereby descramble it.

Abstract: ABSTRACT "Liquid crystal display device"     In a matrix display device having a cholesteric liquid crystal the bistability effect is used which some cholesteric liquid crystals show. The liquid crystal shows a frequency-dependent relaxation of a positive to a negative dielectric anisotropy. After writing the information the light-scattering picture elements have a focal-conical texture and the transparent elements have a homeotropic-nematic texture. The information can be stored for a longer period of time by causing the homeotropic-nematic texture of the transparent elements to change into the substantially transparent planar-conical texture. This is produced rapidly by applying across all picture elements a voltage of a frequency at which the liquid crystal has a negative dielectric anisotropy. The focal-conical texture of the light-scattering elements is substantially not disturbed by said voltage. During the presence of said voltage the written information is continuously visible.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to macromolecular compositions crosslinked by a novel bridge having the formula -NRx-CH=N-CO-.  This novel bridge is obtained by reacting a macro-molecule, preferably a polymer, having at least two amidocarbonyl groups with a compound having at least two formylamido groups in an aqueous medium under highly acidic conditions.  The crosslinking bridge formed by the reaction of this invention is produced in accord with the following formula:       Compositions containing macromolecules having at least two amidocarbonyl groups and a compound having at least two formylamido groups can act as vicosifying or gelling agents for aqueous acids where when added to aqueous acids, crosslinking occurs.  Acids gelled in this manner have important use in the recovery of oil and natural gas from subterranean formations.

Abstract: ABSTRACT          In the intermittent forward feeding of a material web provided with transverse crease lines and simultaneous punching of holes into the material web in a definite relation to the crease line pattern, it is important to ensure that any faults in the length of the forward feed, which occur owing to unavoidable inaccuracies, do not accumulate during working over longer periods, since this would lead successively to ever increasing faultiness in the placing of the holes. The invention provides a met-hod and an arrangement adapted to avoid the accumulation of such faults.          The method is based on that the material web during each forward feeding is advanced a distance which exceeds the correct distance between two transverse lines by the fault margin, so that subsequently, before the next foward feeding, it is restored to a correct position, not affec-ted by any faults in the distance between the crease lines.          An arrangement for the carrying out of the method com-prises, beside a driving element in the form of a driven roller    situated in contact with the material web, also a register-holding element      which comprises drivers    , which engage with the transverse crease lines    , and which after each forward feeding, with simultaneous disengagement of the driving element, res-tores the web a certain distance so as to place the crease lines into the said correct position.

Abstract: ABSTRACT OF THE DISCLOSURE     A motor control circuit for submersible pumps has fea-tures to prevent restarting while the electric motor is back-spinning. The circuit includes a sensor for sensing the voltage produced by the residual magnetism in the rotor of the motor while it backspins.   The voltage sensed is amplified, then rectified and compared with a reference voltage that is preset. The reference voltage corresponds to a voltage produced during backspinning at a selected maximum amount tolerable when re-starting. The DC pulses are filtered to provide a corresponding voltage, then compared to the reference voltage.  The control circuit is disabled from allowing a restart, either manual or automatic, when the corresponding voltage is greater than the reference voltage.

Abstract: ABSTRACT       Catalytic particles with an inert, corrosion resistant support material are provided with a catalyst finely dispersed in a matrix of an insoluble, electrically conducting polymer formed in situ on each particle of inert support material. The inert support particles are catalytically activated by; wetting them with a solution containing an inorganic precursor for the catalyst and an organic precursor for the insoluble, conducting polymer; drying; and heat treating to convert the precursor to the catalyst dispersed in the insoluble, conducting polymer.  An electrode, e. g. an oxygen-evolving anode, is produced by either fixing the catalytic particles to an electrode base, e.g. lead, or by consolidating the catalytic particles into a porous electrode body.

Abstract: TITLE               STRING LOAD APPORTIONED RACKET            ABSTRACT          Longitudinal strings 15 or 25 of tennis or other sports rackets 10 or 20 are lengthened to be at least 30% longer than transverse strings 17 or 27 and are strung with at least 30% more tension than the transverse strings. The longitudinal strings are also functionally related in length and tension to the transverse strings to effec-tively apportion to the longer longitudinal strings from approximately half to substantially more than half of the string force for decelerating a ball penetrating the string network as the ball is hit.  The functional rela-tionship for selecting appropriate lengths and tensions for the longer and shorter strings is mathematically derived, analyzed, and related to practical working mechanics of a string network.  The advantages of lengthening 9 tightening, and apportioning more of the load to the longitudinal strings include a higher coefficient of restitution for the string network; a larger and more responsive sweet spot area; smaller hysteresis losses from string stretching; less interstring friction and ball deformation; higher velocity ball rebound; better shot control; and less torque shock to the arm of the user from off center hits.
